Sometimes you shoot videos or take photos only to find it's vertically oriented. When you are editing those photos and videos in iMovie, you want to rotate them. And sometimes, you just need a certain part of the video frame, so you need to corp photos and videos to remove the imperfect part, focuing on the specific part. If your PC is Windows rather than Mac, you can check this tutorial about how to crop videos on Windows.
When editing videos or photos with iMovie, chances are that the format isn't supported by the software. Thus you should convert them first. So to help you crop or rotate photos and videos in an easier way, I recommend another video editing tool –Wondershare Filmora for Mac(Originally Wondershare Filmora for Mac). It's an easy-to-use yet power-packed Mac video editing tool that supports almost all the popular video and audio formats! Now let's see how to use to crop and rotate videos as well as photos.
Step 1. Import your media files
Go to File > Import Media or just drag and drop photos, videos to the program. To help you easy get files, a media browser is provides to let you import from iTunes library, Photo Booth, etc. You can also record videos using a video capture device or with the built-in iSight.
Step 2. Crop videos and photos
Click the "Crop" button on the tool bar. In the pop up window, choose "16:9" or "4:3" option to crop automatically, or choose "Manually" and customize the size window to crop manually.
Step 3. Rotate videos and photos
Click the "rotate" button on the toolbar to rotate the videos as you like. Alternatively, you can also right click the file and choose the "rotate" option. Rotating 90 degrees clockwise or anti-clockwise, flipping horizontally and vertically are all available.
Step 4. Save your files
After cropping or rotating your videos or photos, click "Export" to save the file to new format or upload to YouTube and even burn to DVD.
Open your iMovie project first and open the cropping and rotating tools. Hit the Crop button on the iMovie toolbar to open the Cropping Tools in the viewer.
Step 2. Crop photos and videos
In the cropping tools viewer, simply drag to resize and reposition the green area to focus on a certain part. Then move the pointer to a corner of it until the pointer turns into a plus sign, and then drag to make it bigger or smaller so as to change the size.
Tip: You can hit Allow Black to maintain a black border around your still photo. This function applied only to still photos.
Step 3. Rotate photos and videos
Hit the Rotate button to rotate your videos and photos to the left or right. Each click turns your image 90 degrees.
Note: With the new orientation, the image might no longer fit the project's aspect ratio, and black bars might appear at the top and bottom of the image (letterbox) or on its left and right sides (pillarbox).
